/* ============================================================================
   HERO UPGRADE — scoped to the landing screen only.
   Nothing here touches the nav, footer, colours, typography or any other
   section. It (1) grades the bright website-build clip down into the site's
   dark #070707 world, (2) adds a cinematic black -> light-sweep brand reveal,
   (3) melts the fold into the film section, and (4) provides three hero looks
   switched by a class on .landing:  .hero--v1 / .hero--v2 / .hero--v3.
   Uses only the existing design tokens (--bg, --ink, --accent, fonts).
